WAV E I N T E R F E R E N C E The e ffec t o f mo irĂŠ c an be se en in many diffe re nt a nd unintende d situations. Caused by wave inte rfe rence patterns, the aim o f this pro ject was to utilise the plasticity of the wood vene er provide d to c reate a physical re pre sentatio n o f no t only the waves, but the wave interference as we ll.

CODE

Bo rder parameter determine s the gap between the e nd o f the cut line and the edge o f the shee t Waves parame ter de te rmines how many co lumns o f c ut lines Diameter parameter determines the size o f the ho les at the e nd o f e ach cut line

Using the input parameters, the python script calculates the dimensions for eac h cut and repeats them down the width of the sheet. The resulting lines are shown above.

E X P E R I M E N TAT I O N Give n the limited amo unt o f ve neer provided, o nly three parame te rs were te st: strip length, strip width, and presence o f ho le s to preve nt te aro ut

Laser cut sheets with various parameters

Veneer was soaked in water for several minutes, then a form was inserted to create the wave shape

5mm strips

7.5mm strips

3 waves with holes

2 waves with holes

2 waves without holes

E X P E R I M E N TA L R E S U LT S

10mm strips

PREVENTING TEAROUT Tearout is visible in piece s witho ut ho les at the end of cut lines, c aused by the excess ive twisting w hich splits down the wo o d grain

R E S U LT : M O D U L A R I T Y The re pe ating wave patte rn alo ng e ach she et, co mbin ed with the laye ring of multiple she ets allows for infinite sc alability

PERMEABILITY The inte rsec tio ns o f waves create s a visual texture, with shades of light and dark dancing as the viewe r moves aro und the artefact

ELASTICITY The re pe ating wave-like structure acts like a spring when load is applied, a result of the manipulatio n o f the fo rm o f individual layers by th e wate r treatment

SCALABILITY The spatial sc ulpture/structure can be visualised at differe nt sc ale s, allowing it to be se en from new pe rspec tives
